TLV9052 RRIO Op-Amp

Texas Instruments' TLV9052 is a dual op-amp that is optimized for low-voltage operations ranging from 1.8 V to 5.5 V. The inputs and outputs can operate from rail-to-rail at an ultra-high slew rate. The device is perfect for cost-constrained applications where low-voltage operation, high slew rate, and low quiescent current is needed. These applications include large appliances and control of three-phase motors. The capacitive-load drive of the TLV9052 device is 200 pF, and the resistive open-loop output impedance makes stabilization easier with much higher capacitive loads.

The TLV9052 is easy to use due to it being unity-gain stable, including a RFI and EMI filter, and being free from phase reversal in overdrive conditions.
